Speclilcation of Letter's Patent. Patented Aug. 29, 1911.

. Application filed February 23, 1910. [Serial No. 545,488.

To all whom it may concem:

Be. it known that We,-WILLIAM L. W1Lcox and WILLIAM J. BENSON, citizens of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented .a new and useful Improvement in Rotary Meters, of which the following is a specification.

This invention relates generally to rotary meters and although particularly adapted for gas can also be utilized as a water meter.

The object of our invention is to provide an exceedingly simple construction of meter,

' equally as well under low one that can be quickly and easily attached to the gas main or pipe and one which can be arran ed in either'a horizontal or vertical position and a still further object of the invention is to provide one in which all the moving parts are so arranged' as to reduce the friction to a minimum thereby pro 'viding an exceedingly easily operated apparatus so that the device will operate pressure as under high pressure. 7 i With these and various other objects in view, our invention consists in the novel features of construction hereinafter fully described and pointed out in the claim,

In the drawings forming a part of this specification: Figure 1 is a vertical sectional v1ew of a rotary meter constructed in accordance with our invention. Fig. 2 is an end view, and Fig. 3 is a transverse sectional view on the line 3-3 of Fig. 1.

In carryin .out our invention, we employ a section of rass tubing A having a collar B at each end, said collar being externallythreaded at B for connection with the gas main or pipe. The collar is also internally threaded as shown at B in order to receive a ring C which carries, a bearing D by means of the spider arms D there being three in numbenthus permitting a ready flow of gas through the meter. i

E indicates a spiral preferably constructed of aluminum and of such an exter-' nal diameter as to fit snugly within the tube .rigidly fastened to the opposite ends of said their reduced ends F journaled in the earings D, said bearings having anti-friction balls arranged therein to reduce the friction to a minimum. It will also be noted that each bearing D ratchet F which is adapt provided with a lubricant receiving socket .or cavity D in which any suitable lubricant,

such as Vaseline is placed and a screw cap D is provided to screw 11 on said socket for the purpose of retainin t e lubricant therein. One of the shafts is rovided with a to be engaged by a depending pivoted pawl F, the purpose of said paw vent the spiral rotating in the reverse di- -rection. Upon the opposite shaft F is arranged an arm G which is of such length as to engage the depending portion of a star wheel H, said star-wheel constituting a part of the registry mechanism audit will be noted that thls registrymechanism is arranged in a case I formed upon the top of the tube A and/this star-wheel H transmits motion to its neighboring wheel H and in that manner the entire registering system. is carried out, the general construction of said register being the same as those now in common use for indicating the total amount of gas passing through the meter. It will'be understood that the gas passes through this meter in the direction indicated by the arrow and in so doing rotates the spiral and this in turn operates thearm G which contacts with the star-wheel H and operates the register.

By reducing the number of parts to a minimum and arranging the shafts upon ball bearings abundantly lubricated we reduce thefriction to a minimum and at the same time we protect all of the parts against dirt and-other foreign matter which would ordinarily impair the meter and by doing away with caring we provide a device cheap and simple to construct and highly eflicient in operation. The device can also be quickly and easily attached by anyone 'The spiral can be made of other metal than aluminum if so desired and any suitand ratchetbeing to preable metal can be employed for the outside casing.

Having thus fully described our invention, what weclaim as new and desire to secure by Letters Patent, is

A device of the kind described com rising a cylinder open at each end an teriorly threaded adjacent the ends, exteriorly threaded rings engaging said threaded end ortions, bearings carried by said rings, eac of said bearin s having an inclosed lubricating socket, anti-friction devices mounted in said bearings, a s iral comprising star wheels at right an1es to 10 blade extendin substantially thelengt of each other, and radial arms carried ythe the cylindrlca casing, shafts secured reother shaft and adapted to engage one of sfimctively to opposite end portions of'said said star wheels.

ade and journaled res ectively in said WILLIAM. LLEWELLYN WILGOX. bearings, a ratchet forme upon one of said WILLIAM JOSEPH BENSON. shafts, a pawl pivotally mounted within the Witnesses: casin and engaging said ratchet, a 'register- A. DUFFNER,
